"To @ZZ wh-m t may concern.' v

Be it known that I, ALBERT CHARLES DA- vis, a lsubi ect of the King of England, residingat Bootle, Liverpool, in the county of Lancaster, England, have invented new and useful improvements in or Relating to ce lVlakinO` A )paratus of which the followin i L', l.- v A v moulds.v chambers, or compartments are.

formed, some, or all of which plates constitute freezing walls for saidcoils;

ln a preferred mode of removably,or -detachably connecting said vplateswith said columns or iiprights, longitudinal Vsocket grooves, cavities,;or recesses are formedA or providedin the latter, inwhich endsV or sides of saidplates are f' adapted to lit and` slide;v

and it 'preferred thatl said longitudinal socketscf the columnspor uprights 'shall be formed at suchl an angle'or inclination that wwhen y'said plates are assembled' 1and posior uprights are preferably such that the coil,

tioned, moulds, chambers' or compartments` of tapering Vshape ork configuration are formed, so that ice ,blocks formedA therein may, after the @thawingllof ,the tank,'be

'A readily withdrawn therefrom,

Further, the construction and I arrangement of the freezingcoils .andsaid columns enclosing wall plates, when positioned in the tank, are in close contactwith the' top anda short distance from thebottom of the coils.

l will further describe my invention with Y the aid of the accompanying` sheets of explanatory drawings, which illustrate, by way of example only, one mode of embodying same. Y

f In said drawings Y Fig. 1 is an elevation` broken away in part in Vorder to expose the interior, of a portion 'Specification of Ylesters-:Patent. i

' .Y 'Said coils d ande are sfo/bent as to flat grids, the coil components 'being inter,-

or carbon cli-oxide through one of the coils; v10,0 preferably in oppositefdirection to tha-tjoff of each unit and brine through the other, and
